Agronomic performance of erect and semi-erect cowpea (Vigna unguiculata (L.) Walp.) genotypes in the Bragantina Region of Pará, Brazil
Abstract
Cowpea (Vigna unguiculata (L.) Walp.) is regarded as one of the most important and strategic food crops in the North and Northeast regions of Brazil, with a national average grain yield of 366 kg ha⁻¹ and approximately 1,000 kg ha⁻¹ in the state of Pará, particularly in the Bragantina region. In recent years, cowpea cultivars with high yield potential have been released. The introduction and evaluation of new lines and cultivars, aiming to identify superior genetic materials in terms of grain yield and market acceptance, have been widely adopted by cowpea producers. This study aimed to evaluate the agronomic performance of 12 lines and five cultivars of cowpea with erect and semi-erect growth habits, in order to identify genotypes suitable for recommendation for cultivation in the Bragantina region, in the state of Pará. The experiment was conducted using a randomized complete block design, comprising 17 treatments and four replications. Grain yield data were subjected to analysis of variance (ANOVA), and means were compared using Tukey’s test at the 5% probability level. Statistical analyses were performed using Sisvar software, version 5.6 (2015). In the 2013 growing season, the line MNCO4-795f-153 stood out, with a grain yield of 1,523 kg ha⁻¹. In 2014, as well as in the combined analysis of both years, the line MNCO4-769f-62 exhibited superior performance, with mean yields of 1,295 and 1,401 kg ha⁻¹, respectively. Overall, the results indicate that the 17 evaluated cowpea genotypes exhibited high yield potential, exceeding 1,000 kg ha⁻¹, and can be recommended for cultivation under the edaphoclimatic conditions of the Bragança region, in the state of Pará.
